To all whom it may concern.-

Beit known that I, JOHN FISCHER, a citizen of the United States, and a resident of Oconomowoc, in the county of Waukesha and' State of Wisconsin,have invented certain new and useful Improvements in Cultivators; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide simple economical four-Wheel gang-cultival tors', each organized to be readily turned and longitudinal section of the same; and Fig. 3,

an elevation of the rear portion of said cultivator, partly in section, looking back.

Referring by letter tothe drawings, A indicates the rear and B the front axle for the wheels O of the cultivator, these axles beingA cranked at their ends. The rear axle is loose in a split bearing b at the rear end of a center reach D, having a segmental rack D integral or otherwise rigid therewith over/said axle, and a cross-head E, fast to the forward end of the reach, has a vertical central clevis c, connected by a pivot-pin d with an arm F, having the other end thereof in the form of a split bearing e, in which the front axle is mounted. In pin-and-clevis union with the cross-head arms are rearwardly-divergent zigzag bars G, having split bearings f on the rear axle between collars g of the same, and the shanks I-I of a series of shovels H are bolted or otherwise rigidly secured to each bar at intervals of its length to be alternately on different parallel lines.

Fast on the rear axle are lateral branches 71. of standards I, between which a lever .I is bolted, and guided in a lug 7l of the lever is a latch K, engageable with rack D', this latch being connected by a link-rod j with a handle L, pivoted to the upper outer portion of said lever. A link-bar M has its rear end in pivotal connection with ears 7s of standards I between the same and is guided between upwardly-projecting branches m of cross-head E, its forward end being a clevis n, connected by a vertical pin p with a shackle N in pivotal union with cranks P, having lateral branches q fast on the front axle, this axle being loose in the eye branches Q' ofthe draft-pole Q of the cultivator.

From the foregoing it will be readily understood that the cranked front and rear axles are adjustable by movement of lever .I to regulate the depth of all the shovels I-I in the ground or to lift them clear of the surface, the adjustments being maintained by the engagement of latch K with the rack D adjacent thereto. It will also be readily understood that the front truck of the cultivator can be swung very short in either direction without cramping, and consequently the whole machine can be readily turned in comparatively little space.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A Wheel-cultivator comprising cranked rear and front axles, a center reach loose at one end on the rear axle and having its other endin pivotal cross-head union with an arm loose on the front axle, rearwardly-diverging zigzag bars in union with the reach crosshead and loose on said rear axle, shovels having shanks rigidly connected to each bar at intervals longitudinally of the same to be alternately on different parallel lines, a lever in rigid connection with the aforesaid rear axle, a lever-latch engageable with a segmental rack portion of said reach, cranks fast on said front axle, a link-bar in pivotal connection with said lever, and a shackle having its ends in pivotal union with the link-bar and cranks, the joint between said link-bar and shackle being such as not to interfere with swing of the front truck of the machine in either direction.

2. A wheel-cultivator comprising cranked rear and front axles, a center reach loose at one end on the rear axle and having its other end in the form of a cross-head provided with upwardly-extending branches,- an arm loose ,on the front axle and in pivotal connection with the crosshead, rearwardly-diverging zigzag bars in union with the arms of said cross-head and loose on said rear axle, shovels having shanks rigidly connected to each bar longitudinally of the same to be alternately on dilerent parallel lines, a lever in rigid connection with the aforesaid rear axle, a lever-latch engageable with a segmental rack portion of said reach, cranks fast on said front axle, a link-bar in pivotal connection with said lever guided between the crosshead branches, and a shackle having its ends in pivotal union with the link-bar and cranks, the joint between said link-bar and shackle beingfsuch as not to interfere with swing of the front truck of the machine in either direction.

3. A wheel-cultvator having cranked rear and front axles, a reach and arm in pivotal union loose on the axles, cranks fast on the front axle, a lever rigid with the rear axle, a lever-latch engageable with a segmental rack on the reach, and shovel-bars arranged to raise or lower coincident with the adjustment 0f said axles.

In testimony that I claim the foregoing I have hereunto set my hand, at Oconomowoo, in the county of Waukesha and State of Wisconsin, in the presence of two witnesses.

JOHN FISCHER.
